Do you think that there is a scenario where 008_untar.pl and
009_extract.pl pass but this test fails, alerting us to a problem that
would otherwise have gone undetected? If so, what is that scenario?

The only thing that I can think of would be if $decompress_program
--test were failing, but actually trying to decompress succeeded. I
would be inclined to dismiss that particular scenario as not important
enough to be worth the additional CPU cycles.
